EXAMPLE
Consider the number 16. Applying a rotationally ambigrammatic transformation gives the number 91. 16 + 91 = 107. A prime. Hence 107 is part of the sequence.
Consider the number 18. Applying a rotationally ambigrammatic transformation gives the number 81. 18 + 81 = 99. Not a prime. Hence 99 is not part of the sequence.
